The thesis examines the impact of the Charter of Fundamental Rights of the European Union on the administrative procedure in Member States. In the introductory chapters, the developments in the protection of fundamental rights within the European Communities are outlined and the main features of the Charter are presented in greater detail. The key findings on the application of the Charter in the Member States are drawn from the annual fundamental rights reports that are prepared by the European Union Agency for Fundamental Rights. Throughout the entire thesis, strengths and weaknesses of the Charter that would have a significant impact on the administrative procedure are referenced where relevant. Further on, the Author critically examines the impact of the right to good administration (article 41 EU Charter) and the right to an effective remedy and to a fair trial (article 47 EU Charter), both of procedural character, on the national administrative procedure. Finally, referring to examples acquired from the recent case law of the Court of Justice of the European Union and national case law, the Author demonstrates how the Charter impacts the fact assessment procedure, the obligations of administrative bodies throughout the proceeding, the possibility of judicial review of administrative action and the impact on final administrative decisions.
